7 Claims.

This invention relates to a spool and has for one of its objects to provide solid corners between the head and the barrel of the spool where a joint customarily occurs.

Another object of the invention is the provision of a spool in which there will be no joint at the juncture between the barrel and the right-angularly extending head and yet along the entire surface of the barrel between the heads there will be an uninterrupted cylindrical surface.

Another object of the invention is the provision of a spool in which the end or outer surfaces of the heads will be flush as to their middle and edge portions so that the same may be supported upon its end or several spools supported in superimposed relation if desired.

A further object of the invention is the provision of a spool which will be strong and durable as to the securing of its parts in desired position. 1

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings:

Fig. 1 is a central sectional View thru the spool.

Fig. 2 is an end view of one of theheads.

Fig. 8 is a sectional view showing each-of the parts and in their relation just prior to assembly.

Fig. 4 is a sectional view of a fragmental portion of a modified construction of spool.

Fig. 5 is a sectional view of a fragmental portion of a difierent modified construction of spool.

In the formation of spools upon which wire is to be wound and the entire mass annealed, it is desirable to provide a head and barrel so that the stock of one will turn the right-angular corner which usually exists between the head and the barrel making it somewhat rounded and thus eliminating the joint at this point; and in order to accomplish this result I have provided a flange upon the head, with the barrel in abutting relation with the edge of this flange, and have suitably supported the structure so that the joint is located-along the barrel at a point spaced from the usual right angular corner; and I have further strengthened this structure by means of a sleeve and an end plate to cooperate with the head and barrel to secure the parts in position and strengthen the jui i'ction between themand I have also provided t h e ends of the head so that the device when on en 'on a flat surface will be supported at the perip cry of the heads and also at the center thereof by reason of this surface being in a single plane; and the following is a more detailed description of the present embodi ment of this invention illustrating the preferred means by which these advantageous results may be provided:-

With reference to the drawings, I consider the portion l as the barrel which extends to the right-angularly extending portions H which I- designate as the heads. The head consists of a disc I2 which has an open center with the stock about this opening turned inwardly as at l3 prol0 viding a flange and also a portion of the barrel. This flange portion I3 abuts the tubular member 14 which provides the main portion of the barrel. The stock of this tubular member and the flange I3 is of the same thickness so that the inner and outer surfaces at the junction l of these parts will be substantially flush.

A sleeve l6 of a size to just fit the inner surface of the barrel extends across the joint l5 to a substantial extent on either side thereof and is secured in position by spot welding as at I1,

while the outer edge of this sleeve is formed into projections I8 to extend outwardly and thru openings I!) in an end plate after which these projections l8 are headed over as at 2! to rivet the end plate securely in position.

This end plate is of a size just smaller than the head 12 and spot welded thereto as at 34. The outer edge of this head I2 is deflected as at 22, see Fig. 3, outwardly and thenrolled inwardly as at 23, see Fig. 1, to extend over the outer surface of this end plate or wall 20 to assist in binding this end plate to the disc 12 and securing it flrmly as a part of the head.

The end plate 20 is deflected outwardly at its middle, as shown at the offset 24' to provide a surface 25 which is flush with or in the same plane as. the outer surface 23' of the rolled over portion 23, so that this end of the spool provides a surface upon which the spool may rest upon its end or such that several spools may be positioned in superimposed relation. The center portion of this end plate is deflected inwardly as at 26, in somewhat of an inclined manner and stiffened by the offset 21 in its surface. Thru the opening 28 in the end plate and a similar opening in the opposite end plate, there extends a binding tubular bearing member 29 which is upset to provide an abutment 30 with which the edge of the opening 28 engages, while the ends of the tubular binding member are flared outwardly, as at 32, to rivet the heads together. This portion 32 which is flared outwardly comes well inside of the plane of the surfaces 26 and 25 so .that no protuberances are provided to disturb rolling over its end as at 31.

the flat setting of the spool in position onend, while by reason of the abutments 30 and the flaring end of the portion 32 a firm binding engagement is provided and one which supports the central portion of the end plate against the inward or outward forces and maintains the spool in rigid position by reason of the construction and assembly of the parts.

In Fig. 4, I have illustrated a differently formed sleeve 35, the same having no projections, such as l8, for the end plate. It is spot welded in position in the same manner as the sleeve IS. The end plate 36 is differently formed and is provided with an opening at its center thru which the core or bearing member 29 extends and is secured by I have provided upset portions 38 nearer the end of core 29 and in such location that the rolled over portion 31 will bind the end plate 36 and hold it between the rolled over portion 31 and the abutment formed by the upset portion 38.

In Fig. 5 I have illustrated a differently modified construction. In this case, I have omitted the end plate and have provided a sleeve 40 with an end wall 4|. This end wall being oflset slightly as at 42 for strengthening purposes and also to position it in such a plane that when the end 31 of the core is rolled over the wall 4| as above mentioned in connection with Fig. 4, the outer surface of the core will be flush with the rolled over part 23 of the head. Abutments 38 are similarly located in Fig. 5 as in Fig. 4. Thus I provide an end plate formed integral with the sleeve rather than as a separate part and secure it to the head by rolling over the outer edge of the core and head.

Suitable openings 33 may be placed in the heads for the circulation of air therethru and the equalization of pressures due to changes in temperature.

The abutting seam l5 may be ground that no uneven surfaces of the two parts may be provided Thus there is no uneven surface or space at the corner in which the fine wire to be annealed may engage or catch.

The foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only bythe terms of the appended claims.
